'SCREEN .ATTCHllENTLr Ordinarily a screen isplacedinthe inner' vents rattling of the :screen inthe guide-v way. @ther tim-es the screen supports the sash'if it is not; properly hangin-the window frame, and in either instanceengagement of the sashwith the screen is adapted to prevent flies, insects and Aforeign matter :from passing between the screen andfsash. This practice necessitates removing ythe screen when the sash is to be lowered, asin inclement weather, and my invention aims to provide means -whereby the: screen may tbepositionedin the outer;gui'deway of the window frame and held by the sash to exclude iiies, insects, and the elements other than through the screen. Ordinarily a comparatively thin sectional, extensible screen is used, particularly of less width than the guideway of a window frame, and for such screen I have devised an extensible member that may be fitted over the upper edge of the screen to extend into the plane of the lower sash, whereby said sash may be lowered to engage the member and retain the screen in a set position. From this position the screen may be shifted, without removal from the window frame, to permit of the sash being closed.

My invention will be hereinafter specifically described and then claimed,vand reference will now be had to the drawing, wherein y Figure 1 is a front elevation of a portion of a window frame having a screen provided with an attachment in accordance with this invention; i

Fig. 2 is a vertical cross sectional view taken on the line II-IIof Fig. 1 showing the screen positioned so that the lower sash may engage the attachment;

Fig. 3 is a similar view showing the screen shifted so that the lower sash may be closed;

Fig. 4 is a perspective view of the screen attachment, and

Fig. 5 is a similar view of a portion of an attachment having sash engaging prongs.

In the drawings, the reference numeral 1 denotes a window sill having a frame 2 constructed to provide an outer guideway 3 and an inner guideway 4, these guideways being/.ordinarily separated 'by a parting strip5. The .guid'eways Sand ,4 ordinarily accommodate sashesand thelowerv sash has been. designated' 6.

Thefreference numeral 7 denotes,'byvthe way pf an example, Ian extensible screen which is`y ordinarily placed in the guideway 4-so that the .lowers sashmay be lowered ontothe'upperrail or frame 8y of the screen, but-instead otfollowing Vout this usual practice, I intend to place thescreen 7 in the guidewaylv 3. VWith the* screen tofk less width than the guidewayit may be shifted laterallyV thereinfand. in one position,- as will hereinafterappear-'provides clearance Afor a closingmovement ofthe-sash 6 andin another position permits of the sash holding the screen 7 against or in proximity tothe partlng strip 5. y

The screen attachment comprises two telescopic members 9 and 10, each inverted channel shaped incross section with an outer wall 11 of less depth than an inner wall 12 of the member. The inner walls 12 of the members 9` and 10 are formed with lateral flanges 13 and 14 respectively, and the lateral flange 13 of the inner member 9 has a return bend 15 affording a guide and vretaining means for the lateral flange 14 of the outer member 10. As a result of this construction the inner and outer members 9 and 10 areheld in adjoining telescopic relation so that vthe longitudinal dimension of the attachment may be increased or decreased at will to adapt the attachmentto screens of various lengths.

The attachment is adapted to fit over the upper rail or frame 8 of the screen 7 and the members of said attachment are adjusted relative to each other so as toextend from one parting strip 5 to the other. Vhen the attachment is correctly positioned on the screen the flanges 13 and 14 afford a ylateral support and with the screen 7 against the part-ingstrips 5 of the window frame the lower sash 6 may be lowered on to the lateral support of the attachment to hold the screen in position and at the same time form a seal between the screen and sash to exclude the elements, bugs and insects.

As 'shown in Fig. 3 the screen 7 may be shifted outwardly whereby the attachment provides clearance for a closing movement that I have devised means for positioning a screen relative to a window sash modified from the usual practice, vot placing the screen below the sash and lowering the sash on to the screen, by setting the screen in a plane to one side of the sash, and then mounting a member on the screen to extend intoV the path of the lower sash so that said sash may be lowered to engage the member and provide a connection between the oset screen and the sash.

Obviously the telescopic members 9 and l0 will be made of non-corrodible material or finished to withstand the elements and at the same time harmonize with the linish of the screen or window fra-me. The configuration of the telescopic members is susceptible to such changes as are permissible by the appended claims.

lVhat I claim is .1. screenV attachment comprising telescopic longitudinally eXtensible members, each member having the configuration of an inverted channelprovided with a lateral flange, the flange of one member having a return bend to form guiding and retaining meansfor the flange of the other member.

2. A screen attachment as called for in claim l, wherein each member has its flange equipped channel wall of greater depth than the other channel wall. Y

3. A screen attachment comprising longitudinally extensible members one slidable on the other, said members having a configuration to lit over the upper edge of a screen and provide a lateral sash engaging support in a plane below the upper edge of the screen by which the screen may be held in a set position.

4. A screenlattachment as called for in claim 3, wliereinthe sash engaging support has prongs adapted to engage in the sash.

In testimony whereof I affix my signature.
